目的探讨足月顺产第三产程的有效处理措施。方法随机将547例足月顺产分娩产妇分为3组,肌注缩宫素组(A组),脐静脉推注缩宫素组(B组),双合牵引胎盘法组(C组),比较第三产程时间,出血量及胎盘剥离情况。结果 B组、C组在出血量,产程时间,胎盘剥离情况方面和A组比较差异有统计学意义(P<0.05)。结论脐静脉静推催产素及双牵引胎盘法均可缩短正常分娩之第三产程,还可减少产后出血量,减少胎盘残留发生率,减少了宫腔操作几率。
Objective To investigate the effective measures of full-term third-stage labor. Methods 547 pregnant women of term delivery were randomly divided into 3 groups: group with oxytocin (group A), group with oxytocin (group B) by umbilical vein, group C with double traction (group C) Comparison of the third stage of labor time, bleeding and placental detachment. Results The blood loss, labor duration and placental detachment in group B and group C were significantly different from those in group A (P <0.05). Conclusions Both intravenous push of oxytocin and double traction placenta can shorten the third stage of labor in normal delivery, reduce the amount of postpartum hemorrhage, reduce the incidence of placenta residue and reduce the chance of uterine cavity operation.
